Cost of Prenuptial Agreement in Thailand
Legal fees, translation costs, and registration expenses for prenuptial agreements in Thailand.
Overview
A prenuptial agreement in Thailand requires legal drafting, translation, and registration at the Amphur. Having independent lawyers for each party increases costs but significantly strengthens enforceability. Budget THB 30,000–100,000 total.
Cost Breakdown
| Service | Government Fee | Lawyer/Agent Fee | Total Estimate | Notes |
|---|---|---|---|---|
| Lawyer drafting (simple prenup) | N/A | THB 15,000–30,000 | THB 15,000–30,000 | — |
| Lawyer drafting (complex/international) | N/A | THB 30,000–80,000 | THB 30,000–80,000 | Complex asset structures, multi-jurisdiction |
| Second lawyer (for other party) | N/A | THB 10,000–30,000 | THB 10,000–30,000 | Recommended — strengthens enforceability |
| Thai-English translation | N/A | THB 2,000–5,000 | THB 2,000–5,000 | — |
| Amphur registration (with marriage) | Free | N/A | Free | Registered at same time as marriage — no additional fee |
| Notarization (if needed) | THB 500–2,000 | N/A | THB 500–2,000 | — |
Additional Costs to Consider
Asset valuation fees if complex property is involved
Courier or travel costs if parties are in different locations
Future modification (requires court approval after marriage): THB 20,000–50,000
Money-Saving Tips
A simple prenup for straightforward assets can be done for THB 15,000–20,000 with one lawyer.
Having BOTH parties share one lawyer is cheaper but weaker legally — avoid for high-value assets.
Draft the agreement well in advance of the wedding to avoid rush fees.
Costs are estimates for 2026. Actual fees depend on complexity, asset values, and law firm. Always obtain a written fee estimate.
